Looking for a fantastic effect? This is really fabulous! The penetration of glass which beats all others. Magician exhibits a Lucite glass frame with a trap door in center of glass. Trap door has a hinge allowing performer to open it and show glass to be solid. Trap is closed and performer immediately passes a dove, balls, or handkerchiefs through the glass. Can be done surrounded. The penetration takes place in the very center of glass. No false moves are necessary. BEAUTIFULLY MADE! Trap door has two special locks so that the "trap" is held closed. Entire effect is laminated and the trap has a replaceable insert. Probably the BEST version of this effect ever built!
